Unprecedented suspended solids load caused by record-breaking extremes in southern Brazil: the May 2024 event

Frontiers in Marine Science
In May 2024, intense precipitation and flooding impacted southern Brazil in what became the country’s worst climate disaster. The unforeseen volume of runoff was funneled into Patos Lagoon, the world’s largest choked coastal lagoon, transporting large ...

Caracterização das atividades econômicas tradicionais no entorno das marismas no estuário da Lagoa dos Patos (RS)

Desenvolvimento e Meio Ambiente, 2010
Salt marshes are predominant intertidal coastal ecosystem in 29º S and higher latitudes. At Patos Lagoonestuary (RS), 6.837 ha of salt marshes occupy margins and islands that have been used by farming and ranching since XVII century.

On characteristic hydraulic times through hydrodynamic modelling: discussion and application in Patos Lagoon (RS)

Revista Ambiente & Água, 2020
Although the analyses of characteristic hydraulic times are important diagnostic tools for studying water mass exchanges and identifying areas prone to stagnation that are potentially subjected to eutrophication effects, their concepts and uses are often

Evidence of habitat fragmentation affecting fish movement between the Patos and Mirim coastal lagoons in southern Brazil

Neotropical Ichthyology
The communication between the Patos and Mirim lagoon systems occurs via a natural channel called São Gonçalo. In 1977, a dam was built in this channel to prevent entrance of saline waters from Patos Lagoon estuary into the Mirim Lagoon.

The Contribution of Waves in Mixing Processes of the Patos Lagoon Plume

International Journal of Geosciences, 2012
The analysis of wave effects above salinity is important in order to define mixing processes and their potential to change density gradients, since action in the region of the Patos Lagoon plume is highly dynamic. This paper aims to evaluate the influence of waves on the mixing pattern of the adjacent continental shelf.

The Exchange Processes in the Patos Lagoon Estuarine Channel, Brazil

International Journal of Geosciences, 2011
Investigation of process controlling the estuarine-shelf interaction in the Patos Lagoon estuarine channel is accessed using a two-dimensional numerical model. Results obtained suggest this approximation provides good precision level to investigate the advective transport of oceanic waters near the estuarine mouth. The introduction of coastal waters in
